Neighbors of the Core 4 bicycle event told the Johnson County Board of Supervisors on Aug. 28 that parking tied to the race blocked a county S-curve for much of the day, stopped mail delivery, and impeded farm and emergency access, and one resident said low-flying helicopters frightened cattle and left a missing animal.

The concerns matter because residents described blocked rural roads, pedestrians and riders sharing narrowed lanes, and restricted access for ambulances and farm work — problems that speakers said could cause injury or property loss.

"I do not know if you're familiar with the S curve on *********** Road, but they had cars parked ... from 10 in the morning to 5," resident Loren Dvorski told the board, saying mail was not delivered that day and vehicles remained parked on the curve. Another resident, who identified herself as Virginia (surname spelled in the transcript as V E D E P O) of Orchard View Estates, said she photographed cars parked abreast on Fingerbury Road that reduced two lanes to one and forced pedestrians and bicyclists into the roadway, and said emergency vehicles would have struggled to get through.

Several speakers said the race organizer had advised parking on nearby orchard property but that space became unusable after rain. "He should have been able to supply better parking than the road," Kathy Dvorski told the board, asking whether the event permit required dedicated off-road parking.

Separately, a different resident, identifying himself as Kyle Shugman, told supervisors he was not seeking to stop the bike race but urged action on helicopters he said were flying very low over private land. "I'm not trying to shut the bike race down ... but you gotta do something about the helicopters," Shugman said, adding he had filed a complaint with the Federal Aviation Administration and cited Iowa Code 328.41 as a state statute that mirrors federal rules on aircraft operations.

Zachary Hall, who said he is a local cyclist and a Core 4 participant, urged cooperation between the event and neighbors: "Anything that could be done to make it better and safer ... I think everyone that is involved with the event would be welcoming of those comments." Hall said many participants are local and that the event draws family riders as well as out-of-area competitors.

Board action during the meeting was limited to acknowledging receipt of written correspondence about the event (an email dated Aug. 18, 2025 from Virginia DeBeko and an Aug. 21, 2025 letter from Kathy and Laverne Divorski) and taking public comments under advisement. The chair said the board would distribute submitted photos and letters to supervisors.

Speakers pressed county staff and law-enforcement presence, and several residents asked for no-parking signage and greater traffic control at narrow curves next year if the event proceeds. Supervisors did not adopt new rules or issue permitting changes during the session; the transcript records no formal motion to change event permits or to order enforcement actions at this meeting.

The board recorded the public comments in its minutes and directed staff to distribute the submitted photos and correspondence to supervisors; supervisors said they would follow up as appropriate after reviewing the materials.

Residents who raised concerns provided photos and asked to be contacted; the board indicated it had some contact information and would reach out where appropriate.
